I moved the thread to the right location.

AS far as your servos, is this a flybarred or a flybarless helicopter..?

When you said you centered the servos, where and how did you center tham, if you dont mind me asking.

If flybarless.. are you using a 3GX?

 

[john2012]

this is flybarred i centered them by rx and binded the tx to my 8000 layed them in the table and like tony did in his build with his 450 3gx did i do this right

OK .. so on the bench were the servos moving the right directions before you did the centering using tx subtrim ?

If so, then check your pitch curve and see if that is still the same as when you centred everything. Check for servo being reversed. Or you hooked up the wrong servo to the wrong channel. Because after doing Subtrim, the servo basically them belongs to that channel , so make sure they are hooked up to the right channel.


report back on what you find out

Did you mechanically centre them before using sub trim? You need to take the servo arms off and get them as close to 90º as you can with the sticks centred, before adjusting subtrim.
